目的 探讨中晚期宫颈癌患者同期放化疗中适合中国人的顺铂单药化疗每周方案剂量.方法 ⅠB2~ⅣA期需放疗的宫颈癌患者为研究对象.Ⅰ期临床试验(15例)为剂量递增试验,顺铂剂量以20、25、30、35、40 mg/m2逐渐递增(≥3例/剂量),40 mg/m2后不再增加剂量.依据Ⅰ期临床试验所得出的最大耐受剂量(40 mg/m2)进行Ⅱ期临床试验(36例).盆腔放疗采用三维适形方法.结果 Ⅰ期临床试验剂量递增至顺铂40 mg/m2未出现限制性不良反应.Ⅱ期临床试验中住院的9例患者都完成了6周化疗,门诊治疗的27例患者18例完成6周化疗,19例完成5周化疗,25例完成4周化疗.所有患者都完成了放疗.主要不良反应为1、2级胃肠道反应与白细胞减少.结论 应用顺铂单药每周方案同期放化疗中晚期宫颈癌,大部分中国人能耐受40 mg/m2的同期化疗剂量,对不能住院治疗体质较弱者化疗剂量应适当减量.
目的 探討中晚期宮頸癌患者同期放化療中適閤中國人的順鉑單藥化療每週方案劑量.方法 ⅠB2~ⅣA期需放療的宮頸癌患者為研究對象.Ⅰ期臨床試驗(15例)為劑量遞增試驗,順鉑劑量以20、25、30、35、40 mg/m2逐漸遞增(≥3例/劑量),40 mg/m2後不再增加劑量.依據Ⅰ期臨床試驗所得齣的最大耐受劑量(40 mg/m2)進行Ⅱ期臨床試驗(36例).盆腔放療採用三維適形方法.結果 Ⅰ期臨床試驗劑量遞增至順鉑40 mg/m2未齣現限製性不良反應.Ⅱ期臨床試驗中住院的9例患者都完成瞭6週化療,門診治療的27例患者18例完成6週化療,19例完成5週化療,25例完成4週化療.所有患者都完成瞭放療.主要不良反應為1、2級胃腸道反應與白細胞減少.結論 應用順鉑單藥每週方案同期放化療中晚期宮頸癌,大部分中國人能耐受40 mg/m2的同期化療劑量,對不能住院治療體質較弱者化療劑量應適噹減量.

Objective To define the maximum tolerated dose (MTD) of weekly cisplatin in concurrent chemoradiotherapy for Chinese cervical carcinoma.Methods Cervical carcinoma of stage ⅠB2- ⅣA were eligible for the study.Phase Ⅰ study was dose-escalation trial with 15 patients.All patients received whole pelvic radiotherapy with three dimentional conformal radiotherapy technique. Concurrent cisplatin started from the dose of 20 mg/m2 to 25 mg/m2,30 mg/m2,35 mg/m2,40 mg/m2 for the weekly schedule ( ≥3 patients per dose group) and the doses were steadily escalated to 40 mg/.m2.If the dose was increased to 40 mg/m2 without dose-limiting toxicity ( DLT),40 mg/m2 would be the maximum tolerated dose (MTD).According to the MTD dose from Phase Ⅰ study,we conducted phase Ⅱ clinical trial with 36 patients.Results In Phase Ⅰ study,cisplatin dose was escalated to 40 mg/m2 and DLT had not been reached.Thirty-six patients in Phase Ⅱ study included 9 inpatients and 27 outpatients.All 9 inpatients completed 6 cycles of chemotherapy. In 27 outpatients,18 patients (66%) completed 6 cycles of chemotherapy,19 patients (70%) completed 5 cycles and 25 patients (92%) completed 4 cycles of chemotherapy.All patients completed radiotherapy.Major adverse effects were grade 1 and 2 gastrointestinal toxicities and neutropenia.Conclusions Weekly 40 mg/m2 cisplatin concurrent with radiotherapy is well tolerated when given to Chinese patients with cervical carcinoma. For outpatients with poor performance status,the cisplatin dose needs to be reduced.
